Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple driver assistance systems are provided to support the driver, then the level of support and functionality is improved, but the complexity of configuration and user confusion increases
Solution Approach 1:
The patent combines multiple driver assistance systems into a unified configuration approach. Instead of configuring each system separately, a single assistance degree parameter controls the activation and settings of multiple systems (distance control, lane keeping, navigation, etc.), merging their configuration into one coherent process that reduces complexity while maintaining versatility.
Solution Approach 2:
The assistance degree parameter serves as a universal control mechanism that simultaneously manages multiple driver assistance systems with different functions. This single parameter provides multi-functionality by enabling or disabling various systems based on the selected assistance level, allowing one control element to manage diverse subsystems.
2Adaptability or versatility
If multiple driver assistance systems are provided to support the driver, then the level of support is improved, but the time required for configuration increases
Solution Approach 1:
The system pre-configures multiple driver assistance systems based on predefined assistance degrees. When a driver selects an assistance degree level, the systems are automatically activated or deactivated according to pre-established rules, eliminating the need for manual configuration of each system and significantly reducing setup time.
Solution Approach 2:
By merging the configuration of multiple systems into a single assistance degree parameter, the patent enables simultaneous control of all systems through one selection. This consolidation reduces the total configuration time from multiple individual settings to a single action.
3Ease of operation
If driver profiles are used to re-use settings, then ease of operation is improved, but flexibility in configuring individual systems is reduced
Solution Approach 1:
The system dynamically adjusts the configuration of multiple driver assistance systems based on the selected assistance degree. Rather than using static driver profiles with fixed settings, the system allows flexible activation and deactivation of specific systems depending on the chosen assistance level, providing both ease of operation through predefined levels and adaptability through dynamic reconfiguration.
4Device complexity
If driver assistance systems operate independently, then system simplicity is maintained, but integrated support capability is reduced
Solution Approach 1:
The patent merges multiple independent driver assistance systems into an integrated framework controlled by a single assistance degree parameter. This combination enables the systems to work together synergistically, providing comprehensive integrated support while maintaining manageable complexity through unified control.
